THE BASICS (1) Flashcards
economics
the social science studying how to satisfies people’s unlimited wants with scarce resources - examines the production, distribution and consumption of goods and services and how to maximise welfare.
normative vs positive approach
normative = how should be done
positive approach - how things are done
finance
subset of economics, how to allocate resources over time and under uncertainty
risk
by definition, the future is uncertain
mean-variance model - modern portfolio theory
risk juxtaposed to return
CAPM
capital asset pricing model, what is a theoretically appropriate required return to an asset when added to a well-diversified portfolio.
asset pricing
valuing assets (value of securities)
corporate finance
how firms get funding and how they invest it
household finance
saving/investment decisions made by households
macrofinance
link between asset prices and economic fluctuations
market microstructure
price formation in asset markets
mathematical finance
novel methods and models to analyse financial problems
climate finance
incentives to mitigate/adapt to climate change and carbon pricing
behavioural finance
how psychological influences and biases affect financial decisions
Assumptions in finance
selfish agents, high returns better, low risk better, money now better than money later, security prices make supply = demand, financial innovation focuses on risk sharing and friction reduction, too many variables - models will be unrealistic
real asset
produce goods and services, generate net income to the economy and determine material wealth
financial assets
claims on real assets and hence on the income provided by the latter, each financial asset = financial liability, sums to 0. defines individual income/wealth amongst investors
net national wealth
sum of total real assets only
non financial firms
typically net borrowers, issue securities to investors and use funds to invest in risky projects, the funds can come from profit, banks, private equity, venture capital, private capital, stock market (public company), bond market(large firms)
households
net savers, purchase securities from government and non-financial firms and or depoist in financial firms /banks
government
NET borrower, through issuing bonds when taxes fall short - budget deficit sometimes saves = budget surplus
financial intermediaries
issue own securities to invest in financial assets, act as clearing houses for financial assets and liabilities bringing brorowres and savers together
overseas sector
borrow from overseas when domestic savings < domestic investment = capital account surplus
high liquidity
need to be easy to get back, small amounts low risk
low liquidity
e.g. infrastructure projects, years to get back, high risk
